Almost every bodybuilder knows that it is more difficult to maintain muscles than to become a muscular man, because fitness is never done once and for all, and it is necessary to persist in training and fitness to ensure that the title of "muscular man" will not fall. Unfortunately, however, not every muscular man can have the conditions for continuous fitness. It can be said that training breaks are common in the fitness circle.
Many fitness friends will encounter all kinds of things that happen to them. Because they have been exercising for many years, it is indispensable for them to be unable to exercise in a short time due to accidents. If the stop time is relatively short, the impact on muscles is actually not great, depending on living habits.
If you don't exercise for a week in a row, your body begins to undergo subtle changes: physical strength begins to decline, metabolism begins to decline, and muscles can no longer effectively absorb glucose from the blood. When you stop exercising for 3 weeks, your body's maximum oxygen intake will drop by 4%~20%. Not only that, your muscle mass will also drop, and the capillaries formed by endurance training in the past will also start to decrease.
Generally speaking, after stopping fitness, our muscle endurance and strength will decline, which is certain, because without the requirement of weight-bearing training, muscle density will become smaller, which will make muscle content less and relax. However, whether your figure is out of shape or not, and the speed of it depends on your lifestyle.
